To all whom fit may concern: Be it known that I, FRANK A. SIMONDS, a citizen of the United States of America, re-

siding at Grand Ra ids, inthe `county ofi Kent and State o f lichigan, have inventecli certain new and useful lm rovements in Ra dimer-Valves;- and I doerebydeclare the following to be a full, clear, and exact de# scription of theinvention, such as will enable others skilled in the art to which it Vafppper W` tains to make and use the same. i' i My invention relates to improvementsin radiator valves, and more particularly tol valves 1n the nature of steam` traps` Afor re,-`

l is a pipe connection by which the device communicates with the radiator.

5 is a similar pipe connection by which the device communicates with the return pipe of the heating system when the `device is installed for use. A valvechamber 6 extends inward within the upper 'part of the casepand communicates with the connection 5. In the axis of this chamber, and also in the axis of the case, is a balanced valve. -The lower member 8 of this valve engages aseat in the lower side of the chamber 6, and closes an opening between this chamber and the interior of a downwardly extended tube 7 in the axis of the case and extending to near the bottom of the same. The valve 9 is detachablysecured to the-valveS and is s aced apart therefrom, and also engages-aV tu ular valve seat V16 which is vertically adjustable in the upper wall of the chamber 6 and locked by an annular nut 17 above the same. l

15 is an air chamber above the valve 9 which communicates through a small open-V ing 20 with the interior of the case. This chamber is closed at the top by a removable plug 18 inserted in an opening large enough to permit the valve 9, valve seat 16, and lock nut 17 vto asstherethrough rlhe va ve VQis secured in )lace by a screw 10,. "fi-The valve 8 has a c ownwardly ex- 'tended-stern y11 in the axis of the case and `having angaxlal opening 1n lts lower end shdablein which 1s a guide pm 12 xed in the lower part of the case. On the lower end of this stemll, by means of lock nuts 14, is secureda-potfloat 13, whereby the balanced valve isopened and closed. In the bottom of this floatis Aa ysmall oienin'g 19 'through which the water will slow y pass, but not in suiiicien't'quantity to materially affect theY operaticmV of the device when in use, and sufficient to slowly bring the water inside .and outside of the float to an equilibrium and thus open the valve when the device is out of use, to remove the water therefrom to suchen extent as to avoid -danger of freezing, and also to leave only a small quantity in the lower part ofthe case when the latter is detached and the valve will always be open when there is no steam in the radiator.

'1n operation the water of condensation accumulating in the case outside of the iloat Will raise the same, and close the valve, the pressure' upon opposite sides of the same eing equalized by meansof a'small opening 20, which permits the pressure in the case to be communicated through the chamber 15, valve seat/*16, andnut 17 to the valve 9. When the water ove'riiows into the float 15 sufficiently, the float and valve will drop, thus opening a passage through both the upper andflower Walls to the chamber 6, andthe pipe inserted at 5. When this occurs, the water will be drawn out from the interior of the float, through the lower opening and at the same time air will escape by way of the upper opening. As soon as the float is relieved of the water therein, it will again rise and closetthe valve until another overflow takes place. When no further Water of condensation comes into the device, the Water therein will slowly pass through the small openinglQ and thus' permit the float to drop and open the valve and drain Patented Aug. 31, 1969.

escape freely through the device until followed by sufficient water to again close the valve, when the operation will be resumed.

YBy adjusting the seat 16, the valve may be made to simultaneously and completely close both openings in the chamber 6.

/Vhat I claim is:

l. A radiator valve, comprising a case having an inlet opening, van inwardly Vprojecting chamber in the case having an outlet opening and also having a topopening communicating with the air space ofthecase,

. anda bottom opening communicating with and a bottom opening communicating with the water space of the case, a valve to simultaneously close or open both of said top and bottom openings, a pot float attached to the valve, and a tube communicating with the bottom opening and extending downward within the float. Y l Y 3. A radiator valve comprising a case, an air chamber inthe case and communicating with the upper part of the same, a tube in the case and extending into the lower part of the same, a discharge chamber inthe case and between ythe air chamber and tube, and separated therefrom by upper and lower walls having openings therethrough Yrespectively communicating with the air chamber land tube, a valve to simultaneously open or Y.close said openings, and a pot float attached to the valve to open and close the same and surrounding the'lower end of the tube. Y

4. A radiator valve of the class described, comprising a casing having inlet and outlet openings communicating with the interior Yvalve will be always opened when the device goes out of operation.

5. A radiator valve, comprising a case having a detachable lower portion, and also having a top opening and inlet and. outlet openings near the top, a plug to close said top opening, an air chamber beneath the plug and communicating by a restricted opening with the interior of the case, an inwardly projecting chamber beneath the first named chamber and communicating with the outlet opening, said last named chamber also having .an upper opening communicating with the air chamber and a lower opening communicating with the tube, a balanced valve to close said openings and having a detachable upper member, an adjustable valve seat in the upper opening, a downwardly projecting stem on the valve, a tube extending downward from the chamber and surrounding said stem, and a pot float attached to said stem and surrounding the tube.

6. A radiator valve comprising, a case having an inlet opening and an outlet opening, an inwardly projecting chamber in the case communicating with the outlet opening and having openings in its respective upper and lower walls, a downwardly projecting tube surrounding the opening in the lower wall, a balanced valve having an upper and lower member closing said openings, the upper member being detachable, an adjustable seat in the upper opening, and a float to operate the valve and surrounding said tube.

In testimony whereof I aflix my signature in presence of two witnesses.
